To prepare the tortellini alfredo with grilled chicken breasts, you'll need: 1 1/2 cups ricotta cheese 2 tablespoons Parmesan cheese 1 teaspoon kosher salt 1/2 teaspoon freshly ground black pepper Instructions: Preheat the oven to 450 degrees F. Line a large baking sheet with foil and brush with olive oil. Add the chicken to the foil-lined pan and cook, turning occasionally, until browned on all sides, 8 to 10 minutes. Set aside. Meanwhile, in the bowl of an electric mixer, beat the egg whites on medium speed until stiff peaks form. Gradually add the milk and beat until the mixture reaches stiff peak stage, about 1 minute. Slowly add salt and pepper to taste. Toss to combine.
